MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent Ila 253,798, dated February14, 1882. Application filed January It, 1882. (No model.)

To all whom it may concern:

Be it known that I, RUEL W. WHITNEY, a citizen of the United States ofAmerica, resid-' ing at New York, in the county of New York and State ofNew York, have invented a certain new and useful Mechanical Movement;and I do hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same,reference being hadto the accompanying drawing, and to letters or figures of referencemarked thereon, which form a part of this specification.

My invention relates to means for converting an eccentric rotary motioninto a concent-ric rotary and a secondary oscillating and reciprocatingmotion; and it consists in a certain arrangement and combination ofdevices, as hereinafter more fully described, and spe citlcally setforth in the claims.

The object of my invention is to produce from the rotation of anypower-driven shaft the rotation of a second shaft and the oscillation,vibration, or reciprocation of a third ele mentof machinery-in otherwords, to rotate a second element and vibrate a third element by therotation of a first element of mechanismwhereby in any machinery adaptedto perform any mechanical operation the two rotative and onereciprocative movements of the elements may be utilized in productiveunitary or aggregate results.

In the drawing, which is a perspective of an arrangement of mechanicaldevices involving my invention, A represents the end of a powerdrivenshaft. From the rotation of this shaft I desire to rotate the shaft Band oscillate a lever, U. The shafts are suitably journaled in theframe-work of any machine in which my invention is embodied, and thelever is pivoted to a fixed portion thereof. I obtain the desiredresults by the following means: To the shaft A, I attach in the usualmanner an eccentric, D, to the shaft B a crank, E, and con Vnect thecrank to the eccentric by a rod,'F. The lever U is attached to theframe-work by a pivot at G, and may be provided with trun. nions orbosses g at this point, if desired. Be-

low the pivot G, atH, I pivotally attach a connectinglink, J, which atits other end is in like manner attached to the rod F, at I. At K on rodF, I pivot-ally attach another connecting-link, L, which I may connectto a short arm or extension, 0, of lever O, at M, as shown; or I mayconnect said link L at the pivot G and discard the short arm orextension 0 of lever (J.

This being the arrangement of the elements employed, the operation is asfollows: The rotation of shaft A causes through eccentric 1), alongitudinal and a lateral movement of that end of rod F which isconnected to the eccentric, and these two motions are duplicated andmerged into a rotary movement of said end of said lever during eachrevolution of the shaft. By and through the connecting-link L similarmotions are produced, duplicated, and merged at the other end of rod F,and by and through crank E said rotary movement is communicated to shaftB. Thus the first step in the problem is accomplished.

It will be observed that the lateral movements of the ends of rod F arein opposite directions simultaneously; hence shafts A and B rotate inoppositedirections. Theseoppositelydisposed lateral movements of theends of rod F produce a movement at about the center of its length whichis similar to a movement resulting from oscillating a bar upon a rollingfulcrum at about its center. The pivot K of link L is such a fulcrum,the center of its rolling motion being about the center of the linklengthwise. Hence a similar rolling motion or oscillation must occur atthe other end of link K, and I provide for this by the short arm orextension 0 of lever 0. Beyond the fulcrumpoint of rod F in eitherdirection the movement thereof partakcs more of the rotary characterthan at said fulcrum-point, and this by means of the connecting-link Jis communio cated to lever U, which, being fixed pivot-ally at one end,transforms said rotary movement into a vibratory, oscillatory, orrcciprocatory movement at its other or free end. Thus the second step inthe problem is accomplished. 5 Now, it will readily be seen that theoscillation at the fulcrum-point of the lever F may be merged into itscenter, as that of the lever (J is at G. Hence I may-substitute for thelink L and short arm 0 a link extending directly from pivot K to pivotG, and thereby produce the same resultant motions in shaft B and thefree end of lever O.

The applications of my arrangement of mechanical elements as hereinshown and described are, in themselves alone and in conjunction withsubsidiary and additional wellknown elements, numerous.

In a sewing-machine, A may be the needlebar shaft, B may operate theshuttle, and G the feed, the usual or any well-known mechanical elementsfor the direction and transmission of power being added in a manner wellknown to persons skilled in that branch of mechanical structures; and soin planing, boring, drilling, sawing, shaping, and in all othermachinery where material is fed regularly orirregularly and operatedupon either continuously or intermittently the same arrangement may formthe gist or basis of operation, and I should deem such application aswithin my invention and embodying the same, as I should also the simplereversal in position of my arrangement, when, as for instance, shaft Bmight be the needle-shaft of a sewing-machine, shaft A theshuttle-shaft, and lever 0 might operate either needle, shuttle, orfeed, and still be an embodiment of my invention.

Having described my invention and its operation, whatI claim as new, anddesire to secure by Letters Patent, is-- 1. The combination of shafts Aand B and lever O and means, substantially as shown and described, forrotating shaft B and vibrating lever O by the rotation of shaft A, asand for the purpose set'forth.

2. The combination of a power-driven shaft, an eccentrically-connectedrod attached concentrically to a second shaft and pivotally connected attwo points to a pivoted lever, substantially as shown and described.

3. The combination of a power-driven shaft, an eccentrically-conuectedrod, and a pivoted lever connected at t '0 points pivotally to said rod,substantially as shown and described.

4. The combination ofshaft A, eccentric D, lever F, links L and J, andpivoted lever O, substantially as shown and described.

5. The combination of sh aft A, lever F, shaft B, lever G, andconnecting-links L and K, substantially as shown and described.

In testimony whereof I have affixed my signature in presence of twowitnesses.

RUEL W. WHITNEY.
